Some people want to play Angry Birds or run other Android apps on their BeagleBoard. Of course, you could use the Rowboat Android project as-is, but then you'd have to give up all of their typical Linux/X11 applications available in Angstrom. This project would use an Android-enabled kernel and a combination of both an Angstrom and Rowboat Android file system. The input and display methods required for Android would need to be adjusted to run within an X11 window.

The fundamental challenge is getting it reproducible and integrated into the OpenEmbedded build system for Angstrom and then starting to minimize the wasted file space by sharing libraries. Eventually, even making Android applications run in a window is desired.

Welcome!

BeagleBoard.org hopes to be accepted as a mentoring organization in the Google Summer of Code for 2013!! Here we collect project ideas for the 2013 GSoC.

Background

BeagleBoard.org is a volunteer organization that seeks to advance the state of open source software on open-source hardware platforms capable of running high-level languages and operating systems (primarily Linux) in embedded environments. Born from taking mobile phone processors and putting them on low-cost boards to build affordable desktop computers, BeagleBoard.org has evolved to focus on the needs of the "maker" community with greater focus on the I/O needed for controlling motors and reading sensors to build things like robots, 3d printers, flying drones, in-car computer systems and much more. Past BeagleBoard.org GSoC projects included an RPC framework for heterogeneous processor communication, a transparent USB packet sniffer, ARM optimizations for XBMC, ARM optimizations for FFTs, make-shift pulse-width-modulation and RPC optimizations for OpenCV. BeagleBoard.org has benefited from sponsorship from Texas Instruments, CircuitCo, Digi-Key and others, but avoids any dependence on that sponsorship for sustaining the effort. The project has evolved over the past few years with over 100,000 boards in circulation with developers and strong roots in the Linaro, Yocto Project, Angstrom Distribution and Linux communities---and support for running most major Linux distributions including Ubuntu, Android, Fedora, Debian, ArchLinux, Gentoo, Buildroot and many more.

Students will be expected to demonstrate an understanding of cross-compiling before being accepted, but support for demonstration is available through the IRC channel that typically has about 150 people logged-in, most with sufficient experience to explain the process.

Every accepted student will be sent a BeagleBone Black before the first week of coding for testing their project.

Students looking for ideas

Student proposals can create projects from the following ideas or propose their own project based on their own ideas. From reading about previous Google Summer of Code projects, the key to success is being passionate about your project, so propose something that is extremely interesting to you, even if it not on the list. We will be glad to help students develop ideas into projects on the BeagleBoard IRC or the BeagleBoard mailing list. There are many more ideas of what can be done and we will match projects to students interest and help scope the proposal to something that can be completed in the Summer of Code time-frame.

Mentors wondering where to help

Please start by registering your idea below following the template given by the existing examples. Further, scroll down to the bottom and give everyone a bit of information about your expertise and availability by adding yourself to the table.

Source code generated during the project must be released on github.com (to be cloned to github.com/beagleboard on successful completion).

The registration on http://beagleboard.org/project must include an RSS feed with project announcements and updates at every milestone. Sources for the RSS feed should be blogger.com, wordpress.com, or some other established blog hosting service with known reliability.

To help you to break your project down into manageable chunks and also help the project's mentors to better support your efforts, weekly project status reports should be e-mailed to the project's mentors and the organization administrator (Jason Kridner). Each status report should outline:

what was accomplished that week,

any issues that prevented that week's goals from being completed, and

your goals for the next week.

Students will provide two recorded presentations, one near the beginning of the project summarizing their project goals and another in the wrap-up phase to summarize their accomplishments. Examples can be found on http://beagleboard.org/gsoc.

Students will demonstrate their ability to cross-compile and utilize version control software by creating a "Hello World" application and generating a pull request to https://github.com/jadonk/gsoc-application/tree/master/ExampleEntryJasonKridner. For assistance, please visit http://beagleboard.org/chat or utilize the beagleboard-gsoc Google Group. The "Hello World" application must print your name and the date out in an ARM Linux environment. Freely available emulators may be used to to test your application or you can ask anyone on the chat or mailing list to help you test.

All projects will produce reusable software components and will not be "what I built over my Summer vacation" projects. Including a hardware component is welcome, but the project *deliverable* will be software that may be utilized by a wide audience of the BeagleBoard community.

Ideas

There are several areas needing contributions:Kernel: Improving the state of the Linux kernel including improved ARM/OMAP/Sitara platform support, simplifying the development of add-on hardware for embedded systems and exchanging hardware connectivity information with userspace.Secondary processor support (RPC/gcc/etc.): Enabling usage of DSPs, PRUs, FPGAs, Cortex-M3s, Arduinos, MSP430 launchpads and other attached processing platforms.Scripting libraries and web interfaces: Improving the Bonescript JavaScript library, web-based interface libraries, examples or alternatives in other languages.Frameworks for open hardware projects: Consolidating support for simplified home manufacturing (CNC, 3D printers, laser cutters, pick-and-place machines, etc.), drones/bots (ROS, IMU, video streaming, etc.) or other common tasks.Optimizations to existing userspace applications/libraries: Optimizations to applications and libraries like XBMC to make them run better on resource constrained environments or to take advantage of more specialized processing elements.

PRU virtual machine

Based on Chris Roger's URAPI work to provide a virtual machine for typical Arduino functions that can be accessed from LabView, build a virtual machine to enable PRU programming from Bonescript. The virtual machine is a simple interpreter that loops over the command to perform delay, pinMode, attachInterrupt, analogRead, analogWrite, digitalRead and digitalWrite functions. A simple conditional goto is resolved at load-time and a minimal set of variables are available for use. Support will need to be included for simple expressions, but the pre-parser can break them down ahead of time. Introspection in JavaScript should be used to convert a minimal function definition into source to be fed to a parser and passed to the interpreter on the PRU via shared memory.

Android under Angstrom

Some people want to play Angry Birds or run other Android apps on their BeagleBoard/BeagleBone. Of course, you could use the Rowboat Android project as-is, but then you'd have to give up all of their typical Linux/X11 applications available in Angstrom. This project would use an Android-enabled kernel and a combination of both Angstrom and Android file systems. The input and display methods required for Android would need to be adjusted to run in on a virtual terminal and chroot/chvt would be used to invoke the various user space windows.
